Answer: it will take her 20 minutes to send all 8 texts.
Explanation:
If she sends 8 texts averaging 80 words each, it means that the number of words in the 8 texts would be
8 × 80 = 640 words
Katy can text 32 words per minute on her phone. Therefore, the time it will take her to send 8 texts or 640 words would be
640/32 = 20 minutes.
